How to JUMP on one PE in SIMD mode?
When we compute a condition in SIMD mode, it checks for status registers in both ASTATx and ASTATy. For eg. in below mentioned code: bit set MODE1 BITM_REGF_MODE1_PEYEN; NOP; btst r8 by 0; if sz jump

Find multi channel input microphone input multi-channel speaker output DSP
中文： 现在的项目需要实现从4个麦克风输入声音，同时并行采集4通道音频，并对4通道音频进行相关算法并通过4通道扬声器输出。这个4各通道麦克风输入及4通道扬声器输出是相互独立的。但是4通道采集的音频数据是需要进行相关算法后（算法为自适应算法），再分开4通道独立输出。 问题如下： 1.对于这样的应用场合，请问采用你们的哪款DSP能实现以上功能，以及相关开发板连接？请您推荐一下，谢谢了！！ 2.能否在上
